Objectives: The aim of this study was to evaluate the learning curve of robot-assisted laparoscopy for gynecologic oncologic surgical procedures, regarding post-operative morbidity
Methods: Between February 2007 and October 2010, 225 robot-assisted procedures has been performed by a single team specialized in gynecologic oncology. Dates were prospectively collected. Isolated and poorly reproducible procedures were excluded, so a total of 187 procedures were finally included to assess the learning curve. Three parameters have been used: overall rate of postoperative complications, operative time and number of lymph nodes. CUSUM statistical analysis was used to investigate the learning curve. After determining the number of cases necessary for learning, a comparative analysis was conducted to compare the learning period to the efficiency period.Results: Fifty cases were necessary to master postoperative complications. The operative time evolves in three phases: the learning phase, with a gradual decrease in operative time; the consolidation phase, steady; and the final phase, increasing, corresponding to the introduction of more difficult cases and to the beginning of training program. There was a growing trend in the number of nodes removed. Comparative analysis of the learning period (senior surgeons) and the efficiency period (with increasing involvement of juniors) showed a significant evolution of procedures, and did not reveal any difference in terms of complications (44% vs. 31%, non significant), or mean number of lymph nodes removed (12.3 vs. 13.2, non significant).
Conclusion: Team training of robot-assisted laparoscopy requires an average of fifty cases looking at per operative complications.
